Attempted import error: 'PreviewManager' is not exported from 'dnd-multi-backend'.

See original GitHub issue

Hello there.

I’m trying to build a react application with these dependencies:

“react-dnd-html5-backend”: “10.0.2” “react-dnd-multi-backend”: “5.0.0” “react-dnd-touch-backend”: “10.0.2”

The build scripts throw this error:

Creating an optimized production build...
Failed to compile.

./node_modules/react-dnd-multi-backend/dist/esm/Preview.js
Attempted import error: 'PreviewManager' is not exported from 'dnd-multi-backend'.

I took a look at the dependency tree and react-dnd-multi-backend requires “dnd-multi-backend”: “^5.0.0”. Maybe the last version v5.0.2 introduces this issue? Thank you so much.

Actually, it should have been 6.0.0 as there are breaking changes… Anyway, after a few publishes and npm deprecate, installing react-dnd-multi-backend@5.0.0 will yield you dnd-multi-backend@5.0.1 which are compatible.

Sorry for the confusion! Note that from react-dnd-multi-backend perspective, the only changes between 5.0.1 and 6.0.0 is a new DndProvider component and a usePreview hook, no breaking changes.

If you can confirm everything is working as expected, that would be greatly appreciated 😃

Hi @nan140114,

Ugh, I didn’t think of that at all! I will unpublish the 5.0.2 and republish it as 5.1.0 (as it should have been from the beginning).

Sorry about that!
